The Cell Phone is a key item that is always in Kris's inventory. It can be used several times to attain unique dialogue in Hometown.

At the beginning of the game, the phone has only one number- Toriel's home phone. Calling this number yields different dialogue from Toriel depending on Kris's location:

  • If called from Toriel's home, Toriel picks up but becomes agitated with Kris.
    • If called from the main room, the landline rings. However, narration jokingly states that Kris cannot pick up the phone because they are already on their cell phone.
  • If called from elsewhere in town, Toriel encourages Kris to walk home and reminds them of where her house is located. If called again, she mentions she is busy grading.
  • Toriel calls Kris (alternatively, Kris may call Toriel) on the way out of school following their return from the Dark World. Toriel expresses worry, but is happy that Kris was spending the time with a friend and permits Kris to stay out a little longer.

Additional Uses[edit | edit source]

  • If used in the Dark World, the Cell Phone makes the same sound as W. D. Gaster's entry 17 from Undertale, and does not function.
  • By talking to Sans, Kris can obtain a second phone number. However, when called, it directs Kris to a hotline for idiot babies. The option then changes to "Not Sans's Number" and rings indefinitely when called.
